A rare case of a recurrent leiomyosarcoma of the buccal mucosa

Leiomyosarcomas are rare malignant tumors that affect smooth muscle tissue. In the oral cavity, leiomyosarcomas are exceedingly rare. The diagnosis is challenging due to the overlap of morphologic findings with several spindle cell tumors. Herein, we reported a rare recurrent case of leiomyosarcoma in a 73-year-old woman presenting clinically as a painful nodule on the buccal mucosa. Microscopically, the tumor showed atypical spindle cells with elongated, blunt-ended nuclei and eosinophilic cytoplasm arranged in a fascicular pattern.
